Dalton's law of partial pressures states that the total pressure of a mixture of gases is the sum of the partial pressures of its components:
\text {P}_{\text{Total}} = \text P_{\text {gas 1}} + \text P_{\text {gas 2}} + \text P_{\text {gas 3}} ...P

Common salt besides being used in kitchen can also be used as the raw material for making washing soda and baking soda.
The overall balanced reaction for washing soda preparation:
2NaCl + CaCO3 → Na2CO3 + CaCl2
NaCl is sodium chloride or common salt
Na2CO3 is sodium carbonate or washing soda
CaCO3 is calcium carbonate or limestone
The overall balanced reaction for baking soda preparation:
NaCl + CO2 + NH3 + H2O → NaHCO3 + NH4Cl
Baking soda (NaHCO₃ - sodium bicarbonate) is white, solid, crystalline salt or appears as a fine powder.
NH3 is ammonia
CO2 is carbon (II) oxide

Answer:
<u>yes, this is an acceptable practice in research.</u>
<u>Explanation:</u>
Note that, having a different result in one's research does not imply it is automatically invalid. However, because there may have been some errors or limitations in the previous work by the male researcher, it is possible that the later results are more accurate, even though she used the same procedures. She may have been more careful when calculating her results.
